net growth of domains per day?
 

I was just wondering if anyone knows the number of domains registered per day vs. the number of domains that expire per day.

For example, let's say there are an average of 50,000 domains registered every day, but there are 40,000 domains that expire every day. There would be a growth of about 10,000 registered domains a day. I know this is a bit simplistic, but you get the general idea.

Anyone got stats?
